hibernate-4.x

I have three kinds of primary keys for tables: INT auto generated primary key which use AUTO_INCREMENT capacity from database vendor (MySQL) CHAR(X) primary key to store a user readable value as key (where X is a number and 50 <= X <= 60) Complex primary keys, composed by 2 or 3 fields of the table. Also, there are some group of fields that may be present (or not): version, INT field. createdBy, VARCHAR(60) field, and lastUpdatedBy, VARCHAR(60) field (there are more fields but these covers a basic example). Some examples of above: Table1 id int primary key auto_increment version int value char

I'm trying to set up my project using Spring 3.1 and Hibernate 4. I've been following some tutorials online. I'm getting a strange error that according to the spring forums should have been fixed with Spring 3.1. Spring Bug Tracker When my service calls getCurrentSession() , it throws the following exception: org.hibernate.HibernateException: **No Session found for current thread**] with root cause org.hibernate.HibernateException: No Session found for current thread at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97) at org.hibernate

I am using "Spring-boot + Hibernate4 + mysql" for my application. As part of which I have a requirement where my sprint-boot app should be able to start even when database is down. Currently it gives the below exception when I try to start my spring boot app without DB being up. I researched a lot and found out that this exception has to do with hibernate.temp.use_jdbc_metadata_defaults property. I tried setting this in "application.yml" of spring boot but this property's value is not being reflected at runtime. Exception Stack Trace: 2014-05-25 04:09:43.193 INFO 59755 --- [ main] o.hibernate
